Is it possible to get gcc to ignore unknown -W... command line options?

I have a build configuration that has some "-Wno" options meant to cover both 'gcc' and 'clang'. The problem is that gcc doesn't recognize some of the clang specific ones and fails to compile because of it.

Example of the error:

 error: unrecognized command line option "-Wno-self-assign"

Is there a way to tell gcc to ignore command line options that it doesn't recognize?
